I have searched on this with no results found, but I'm sure someone must have asked this question a million times.

I bought a quart of Minwax Helmsman Spar Eurethane to reseal some interior teak panels that fit into the bilge cutouts in my cabin floor. It has done a real nice job on these pieces and I was wondering how it will hold up on trim up above. I don't have much wood trim on deck and in the cockpit, mostly just the tiller handle and the companionway hatch slats and coaming.
The can claims UV and outdoor protection; does anyone have experience with this stuff used on exterior trim?

I have used minwax spar varnish on hatch board and tiller over a minwax stain.

I get about two years between light sand and recoat of hatch board, but the minwax does not hold up on the tiller, probably to mutch abrasion from use.

It won't hold up nearly as well as something like Interlux Goldspar.

The minwax polyurethane is good for interiors and will hold up well. But, anything that is subject to UV rays won't last more than two seasons (less in high sun areas) without a good spar varnish.

Varnish is simply the best when it comes to sun exposure.

I found this out the hard way after using this product on handholds and tiller in past boats.

Thanks Murph et al.
I will plan to use it only inside the cabin areas and get some good Spar Varnish for the exterior elements.

Spar Urethane...

I say that the stuff is easy to work with, easy on the wallet and works good on interiors as stated above. I will however say that its not truly "marine" as the name implies... Even minwax suggests that you dont use this stuff on exterior boat stuff in the marine environment. Perhaps they should change the name. (But it got you, me and the rest of us to fall for it) I coated up my carolina skiff mahogany with it and it lasted almost the whole season here up in new england but I probably needed more like four coats instead of two. Just not enough time. Heres what it looked like when done, stuff is convincing after applied and for the price served me well but im starting to get tired of all the sanding and doing it twice instead of paying up front. A lesson i've learned many times.

Skiff:
